If you're asking about Java (as your title suggests, though none of your post talks about Java), there is a Java Forum you can post in / ask a moderator to move your thread to. You'll be much more likely to get help there (though I wouldn't hurt to explain in more detail what you're doing, what your environment is and what libraries you have looked at too).

If not, what language are you working with, what environment, tools, libraries, etc.
